Most Japanese workers in Tokyo commute by train from the suburbs, reachable within 60-90 minutes. While a few of the trains are packed, most trains are punctual and have enough space for a commuter to sit/stand comfortably. Most young commuters play games while commuting. This post reviews some of the popular games.
Nice list! I have been gathering bits and places all over Tokyo where I would like to see on my next trip. Going to write a few of these down. I love gaming!
